Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, a shrapnel piercing forming device includes an upper supporting plate 1, an upper footing 2, an upper knockout plate 3, a rubber 4, an upper mold base 5, an upper backing plate 6, an upper splint 7, and an upper stop plate 8. Upper stripping plate 9, upper mold punching rod 10, piercing punch 11, lower template 12, lower backing plate 13, lower mold beating plate 14, lower mold base 15, lower knockout plate 16, lower pad 17, lower Die spring 18, lower mold beat bar 19, puncture interior and take off 20.

[0021] An upper foot 2 is fixedly arranged between the upper supporting plate 1 and the upper mold base 5 , and an upper backing plate 6 and an upper splint 7 are sequentially fixed on the bottom of the upper mold base 5 . Above the upper mold base 5, an upper knockout plate 3 is arranged next to the upper pad 2, and a unglue 4 is a...

Abstract

The invention discloses a spring plate puncture forming device which has the following beneficial effects: according to the sizes of the processed spring plates, the required number of springs are arranged below a lower die knock plate and the lower die knock plate is utilized to support puncture inner strippers. By means of the invention, the problem that when the spring plates are processed in the prior art, the puncture positions of the spring plates are liable to broken holes, thus affecting subsequence processing of the spring plates is solved. The spring plate puncture forming device issimple to operate, has high efficiency, can not cause broken holes, and utilizes the springs to ensure the plates to float up and down to replace ejector pins to strip materials.

Description

[0001] technical field [0002] The invention relates to a hardware mold, in particular to a piercing forming device for shrapnel. Background technique [0003] For the small and dense punctures in the NOKIA shrapnel, the existing puncture method is to use a thimble to puncture and remove the material. A spring is arranged under each punctured internal prolapse, and a thimble is arranged on the spring, and the thimble is used to remove the material. The support is pierced and dislodged. Because the punctures in the shrapnel are small and dense, during processing, two adjacent springs are too close together, which may easily cause puncture holes, affect the quality of the shrapnel being processed, and bring certain difficulties to subsequent processing and molding. trouble. Simultaneously, a spring and a thimble need to be arranged at the bottom of each punctured inner strip, and the parts are used more, and the cost is higher. In addition, the two adjacent springs are too...
